OK, I'll touch on the shipping part. Compared to what the dealer has including rims, I only save less than $100 CDN if I buy in the US AND if I pick them up there too. This is with tirerack and that's buying rims and steelies x4. The cost savings, if any depends on what tire you're buying too. I also seen TireRack jacked up the price of their steel wheels which makes them a luke warm price, at best. As far as buying Canadian goes. Unless you're in some rural part of the country or where the business really is looking out for their customers, people, IMO, should buy where they get their best value. Afterall, business is capitalism. Capitalism is legalized greed -- Conrad Black.
